If it's a one-piece crank, then no. If it's the common two-piece (like newer Schwinns), then the only way to know is measure, measure, measure. At a minimum you will need to take the pedals off to measure the spindle length.

My first suggestion is to read all the previous answers on the UN55 before you attempt to replace your bottombracket assembly. If you can remove the spindle, look to see if the specifications of the spindle are embossed on the spindle itself. For example, my Shimano spindle has specifications of 68 - 122.5 embossed on it, the smaller number is the bottom bracket bearing tube width and the larger number is the actual spindle length. Then select the UN55 sealed bearing BB that is the closest to your measurements.

Well, let me see. If your Schwinn has a conventional crankset connected by a conventional bottom bracket then the Shimano UN55 should work. back in the early days, 1950's and before, Schwinn used to build bikes with a one piece crank. The UN55 won't work on that type (unconventional) of crank. If your Schwinn originally came with a 2 piece crankset with square taper BB interface, the UN55 is correct for you. Now keep in mind that the UN55 X 68MM is designed for a roadbike bottom bracket shell width. If you're dealing with a mountain bike it will be 73MM BB shell width. Also you will need to know the correct spindle length, they vary in length according to what is attached to the crank, drive side. Single, double or triple chainrings. Hope this helps.

Okay, so it's not the model of the bicycle, it is the compatibility of the components that work together. So yes, if you have 3 chain rings in the front and 7 cassette or freewheel cogs in the rear, most likely it will work. However, there are other factors: derailleur (the mechanism that reacts to the pull or push of the shift pod to change "gears") ratio (Shimano is about 2:1 units in the shift mechanism, so you need a derailleur that has the same 2:1 pin/rivet/bolt unit ratio), or something in need of replacement or readjustment.

Yes as long as you use a 7 speed shimano gear selector and your bike has a freewheel hub.

I don't know. I use mine on a spin bike. I just know shimano makes great gear.

I have mine mounted on a Trek 3500 with no issue. Not sure what the difference in frame would be but I would suspect that you would not have an issue

First, I don't know. I have found calling Shimano Customer Service line to be very helpful when I had the same question. But in my experience as long as the number of speeds is the same, and the largest/smallest sprocket size is the same, you should be OK. Again, you should call Shimano to confirm. It is based on the derailleur, and in my case, I discovered from Shimano customer service that I was able to keep my same derailleur when I made my switch.

According to Shimano it is not supposed to work but I have used it with both an Ultegra short cage and a 105 short cage. If you B tension screw is bottomed out with the 12-28 I would guess not but if there is some travel left it should work I think. Frame and hanger geometry can play into it.

it depends if you have a 3 sprocket cassette on the front by the pedals and a 7 sprocket cassette on the rear wheel. if not then no these will not work. you also need to have shimano deraileurs. its the part that moves the chain to switch gears at the sprockets.

Yes. As the product description says " Compatible with all Shimano and Sram hubs ".......slides on a freehub NOT for a threaded freewheel

As long as you have a Shimano deraileur it should work. Make sure you get the 7-speed set for a 21-speed (3 front/7 rear)

Shimano SPD-SL, they work for me on that setup. they DO NOT WORK for the standard SPD peddals. do a quick google on SPD vs SPD-SL

Yes, since it is a Shimano product,it works with a Suntour deraileur kind of, just a little stiff.

It will work, you may need to change to a Shimano shifter and crank set to complete the package. Otherwise you will have issues when shifting up and down.

It should work for you, unless the fork tips on the 7000 are different than any other bike?
